Final (consonant or consonant cluster)
In a Korean language, the consonants come before or after a syllable.
19 consonants, including the double consonants, can all be used in front of a vowel,
but only 16 consonants excluding ㄸ, ㅃ, ㅉ can come after a vowel.
The consonants on the end of a Korean orthographic syllable is called a “final.”
These “finals” only have seven phonetic values which are ㅇ, ㅁ, ㄴ, ㄹ, ㅂ, ㄷ, ㄱ.
